论文摘要
为了解决在在线公众舆论的演化过程中，由回声室效应引起的意见问题和扭曲的问题，提出了一个三维的脱伊斯布赫模型，以研究本文中回声室效应的形成和消除。首先，原始的成对相互作用模型被推广到三点相互作用模型。其次，我们考虑个人心理机制，并将个人情感因素引入原始模型的信任门槛。最后，引入了自然意见系数以修改模型。改进的模型用于对具有不同结构的社交网络进行仿真实验，并将意见领导者和主动药物引入网络中，以研究回声室的相应产生和破坏机制。实验结果表明，网络结构的变化无法消除回声室效应，网络稳定性和连通性的增加只能减慢回声室效应。意见领导者可以在影响力范围内汇总意见，并对观点产生指导影响。因此，如果意见领导者可以随着时间的流逝改变意见，他们就可以很好地指导观点以汇聚为中立的意见，从而实现打破回声室的目的。活跃的代理可以带领网络中的意见融合到中立，而具有高固执的活性药物可以导致自由视图融合到中性，从而实现了打破回声室效应的目的。
In order to solve the problem of opinion polarization and distortion caused by echo chamber effect in the evolution process of online public opinion,a three-dimensional Deffuant-Weisbuch model is proposed to study the formation and elimination of echo chamber effect in this paper. Firstly, the original pairwise interaction model is generalized to three-point interaction model. Secondly, we consider individual psychological mechanism and introduce individual emotional factor into the trust threshold of original model. Finally, the natural evolution coefficient of opinion is introduced to modify the model. The improved model is used to conduct simulation experiments on social networks with different structures, and opinion leaders and active agents are introduced into the network, so as to study the corresponding generation and breaking mechanism of echo chamber. The experimental results show that the change of network structure cannot eliminate the echo chamber effect, and the increase of network stability and connectivity can only slow down the echo chamber effect. Opinion leaders can aggregate opinions within their scope of influence and have a guiding effect on opinions. Therefore, if opinion leaders can change their opinions over time, they can well guide opinions to converge to neutral opinions, thus achieving the purpose of breaking the echo chamber. Active agents can lead the opinions in the network to converge to the neutral, and active agents with high stubbornness can lead the free views to converge to the neutral, thus achieving the purpose of breaking the echo chamber effect.
